What you should know about us

 

Everllence enables its customers to achieve sustainable value creation in the transition towards a carbon neutral future. Addressing tomorrow’s challenges within the marine, energy and industrial sectors, we improve efficiency and performance at a systemic level. Leading the way in advanced engineering for more than 250 years, we provide a unique portfolio of technologies. Headquartered in Germany, Everllence employs some 15,000 people at over 120 sites globally. Our after-sales brand, Everllence PrimeServ, offers a vast network of service centres to our customers all over the world.

We can offer you the following tasks

 

Lifetime and thus the exchange interval is of major importance for aluminum compressor wheels of turbocharger. The reason for this is the temperature field of the compressor wheel resulting from high circumferential speeds and pressure ratios. The material temperatures in combination with the centrifugal forces arising from the rotational speed define the lifetime and thus the exchange interval. Therefore, a reliable lifetime prediction requires a precise prediction of the material temperatures. This work focuses the sensitivity of compressor wheel temperatures on geometrical parameters of the compressor stage and cooling system as well as the sensitivity on thermal boundary conditions of the simulation model.


Content of the work is:

  • CHT computations for evaluating compressor wheel temperatures
  • Comparison of CHT computation results with available measurement data of compressor wheel material temperatures
  • Numerical investigation of the sensitivity of compressor wheel temperatures on selected geometry parameter (geometry of compressor wheel backside cavity)
  • Application of AI methodes to develop surrogate models for temperature prediction

You can help us with these qualifications

 

  • Master’s thesis in mechanical engineering or aerospace engineering or similar
  • Basic knowledge in the field of heat transfer
  • Experience in CFD simulation (preferred with ANSYS CFX)
  • Basic knowledge in turbomachinery is a plus

Your professional home

 

Everllence headquarters in Augsburg were once the setting for the invention of the diesel engine, with which Rudolf Diesel declared war on the steam engine. Today, our primary mission is to overcome the challenges faced by the marine, energy and industrial sectors – not only to ensure our customers’ success, but also to preserve our environment. From small increases in the efficiency of individual components, such as dual-fuel engines, exhaust gas treatment systems or software solutions, to major innovations at system level – every day, around 5,000 employees work at our site in the beautiful renaissance city of Augsburg to create a better future. You too can help us do that. We are the employer for you if you want to make a difference.
